SilveRboard® Graphite

Graphite Polystyrene Insulation

High performing and cost effective non-structural graphite polystyrene (GPS) rigid insulation board for exterior wall applications on wood or steel frame construction. The expanded polystyrene (EPS) core is embedded with graphite particles which increase the thermal performance, compared to conventional EPS.

In addition to the increased thermal resistance, the foam is laminated with a reflective film on both sides increasing board strength and flexibility, reducing site damage and waste. The reflective laminated surfaces are micro perforated giving the panel high water vapor permeance greatly reducing the likelihood of trapped moisture through the increased drying potential. The larger panels and laminated film help improve job site efficiency and reduce labor costs.

Expanded Polystyrene Embedded with Graphite Particles

SilveRboard® Graphite XS can be used as the second plane of protection under exterior cladding when the joints are properly taped and sealed, eliminating the need for an additional membrane. The laminated film comes micro perforated by default (denoted by XS) but is also available without perforations by special order.




Both SilveRboard® 35XS and SilveRboard® Graphite XS are available in a wide range of thicknesses ranging from 1/2″ (13mm) to 6″ (152mm). Standard board dimensions include 4×8′ and 4×9′  (1.2×2.4m and 1.2×2.7m).

Why Use SilveRboard® Graphite?

Durable, lightweight, energy efficient, and environmentally friendly

Superior Thermal Insulator

SilveRboard® Graphite has a high R-value and an exceptional long-term R-value retention. It also provides increased thermal resistance in lower temperatures.

Permeable Barrier

The perforated boards provide high vapor permeance allowing walls to dry out and can act as a second plane of protection when taped and sealed.

Durable, lightweight, flexible

Each panel is easy to handle due to the ultra-low weight and is easily cut.

Improved Indoor Air Quality

SilveRboard® Graphite does not contain CFCs or HCFCs, no off-gassing and does not promote growth of mold and mildew.

Environmentally Friendly

Graphite EPS foam saves energy during manufacturing.

Increases Comfort and Energy Savings

Acts as continuous insulation in the building envelope, reducing thermal bridging and energy consumption while improving comfort.
